the shape of the distribution of the time required to get an oil change at a 20​-minute ​oil-change facility is unknown.​ However, records indicate that the mean time is 21.2 minutes​, and the standard deviation is 3.4 minutes.

Complete parts ​(a) through (c).

​(a) To compute probabilities regarding the sample mean using the normal​ model, what size sample would be​ required?

​(b) What is the probability that a random sample of n=45 oil changes results in a sample mean time less than 20 ​minutes?

​(c) Suppose the manager agrees to pay each employee a​ $50 bonus if they meet a certain goal. On a typical​ Saturday, the​ oil-change facility will perform 45 oil changes between 10 A.M. and 12 P.M. Treating this as a random​ sample, there would be a​ 10% chance of the mean​ oil-change time being at or below what​ value? This will be the goal established by the manager.

1. Consider the aggregate demand/aggregate supply model of Chapter 10. Assume that the long-run aggregate supply curve is vertical at Y = 3,000 while the short-run aggregate supply curve is horizontal at P = 2. The aggregate demand curve is given by Y = MV(1/P), with M = 6,000 and V=1.
   

a) Suppose that there is an adverse supply shock that shifts the short-run supply curve upwards, to P = 3. What are the values of P and Y in the short-run equilibrium after this shock?

b) What changes (if any) in the values of P and Y would take place going from the short-run equilibrium of part A to the long run (assuming no other shocks occur)?

c) If the FED wants to avoid any changes in the level of Y as a response to the supply shock, what should be the change in the quantity of money M?

You consume two goods, X and Y . On Tuesday, the price of Y (not X!!) rises. On Wednesday,
there are no new price changes, but your income rises until you are just as happy as you were
on Monday.
a) Draw your budget lines and optimum points on all three days. Label the optima M, T and
W.
b) In terms of the locations of the optimum points, what would it mean for Y to be a Giffen
good?
c) In terms of the locations of the optimum points, what would it mean for X to be a normal
good?
d) Suppose that X is a normal good, and suppose also that you consume more X on
Tuesday than on Monday. When the price of Y changes, which effect on your
X-consumption is larger: the income effect or the substitution effect? Justify your answer
in terms of the locations of the points on your graph.

a. 500 mol/h methane at 40°C was fed to a furnace and burned with 15% of excess air at
80°C. The exit gas products comprise of CO2 and CO in mol ratio of 15 (CO2/CO), where
all methane was burned during the combustion. The product gas leaves the furnace at
380°C. Determine the amount of heat loss from the furnace in kW.

b. During the combustion process in part (a), the heat produced is used to heat up the water
to produce steam. By considering the changes of the following conditions for the same
process in part (a), predict the changes to the production rate of steam and justify your

“Critiquing the Functions of Managements in the Changing Environment”

The classical functions of management include planning, organising, leading and controlling. While the relevance of these functions has been attributed to the success of many organisations in the past, there has been a doubt on the relevance of these classical functions of management in the contemporary organisations that are witnessing continual changes in their organisational environments.

write an individual report to provide a critical analysis on both how the functions of managements are constraining to the ability of organisations to adapt with the changes in their environment, and how organisations could appropriately (i.e. which types, styles, or theories) plan, organise, lead and control in the contemporary workplace characterised by changing environments.

For this task Demonstrate an excellent understanding of the necessary concepts/ theories involved and also the nature and complexities of problems. Demonstration of the breadth and depth of response, and sufficient and appropriate reallife information to support the key points are excellent.[ should be around 1500 world and plagarism free]

The purpose of this assignment is to identify factors that must be considered when conducting global marketing campaigns.

For this assignment, imagine you work for a U.S.-based organization that sells household appliances and is considering opening stores internationally, starting with Brazil. You have been tasked with providing your recommendations in preparation for the expansion into Brazil. In 250-500 words, address the following:

1. Discuss how you would modify the personal selling approach based upon the Brazilian target market. Provide an example of the specific changes you would make and justify the changes.
2. Identify ethical and regulatory issues that should be considered when marketing in Brazil.

Identify cultural and social considerations you should take into account as part of your marketing planning efforts. Explain how these factors make the marketing presented to the Brazilian audience different from what is presented to U.S. consumers.

First, type the following command:

            sort employee

What is the order that employee is sorted in? ___________________________________________

Give a brief description of how the file is sorted. _____________________________________________________________________________________________________________________________________________________________________________________________________

Now, sort on the field for last name.

        sort +1 employee

Look at the sorted file. Are all the names sorted in alphabetical order? ______________________

Give a brief description of the output.______________________________________________________________________________________________________________________________________________________________________________________________________________

Sort the file again using the following command:

            sort -f +1 employee

What happens when you sorted it this time? ________________________________________________________________________________________________________________________________________________________________________________________________________

Type in:

            sort +3 employee > hired1

Use the cat command to list out the file hired1 to see the results. Are the hire dates sorted in order? _______________  

If not, what has happened? _____________________________________________________________________________________________________________________________________________

Type in:

            sort -n +3 employee > hired2

What is the result of the sort? _______________________________________________________________________________________________________________________________________________

Type in:

            sort -nb +3.4 employee > hired3

What was the result? ________________________________________________________________________________________________________________________________________________

Briefly explain what happened. ____________________________________________________________________________________________________________________________________________

Type in:

            sort +0 +4n employee

What was the result? ________________________________________________________________________________________________________________________________________________

Were both columns sorted? __________________________

Type in the next command.

            sort +0 -1 +4n employee

What were the results of this output. Was the file sorted on both the department and also the salary field?

issue the command:

        sort -n -t: +4 books

What is the result? ________________________________________________________________________________________________________________________________________________

Try another sort using the books file. Sort on the price field in reverse. Type in the following:

        sort -nr -t: +5 books

What was the result? _______________________________________________________________________________________________________________________________________________

Try one more sort, this time saving the sort to a file. This sort will be on two fields. Put it into a new file called newbooks. Type in:

        sort -t: +0 +1 books > newbooks

Look at the file, newbooks. What does the sorted file look like now?
